+Subject: [PATCH] gio: fix compilation without F_{S,G}ETPIPE_SZ
+
+Commit a5778ef7c51044147fe470ea1707dd297f44f880 broke compilation on
+architectures without F_SETPIPE_SZ and F_GETPIPE_SZ such as or1k.
+If those variables are undefined, put back previous behavior, buffer
+size set to 1024 * 64
+
+Fixes:
